An automatic control system for a combustion gas refrigerator comprising a control module, a temperature sensing device and a thermoelectric couple, the thermoelectric couple is connected with the temperature sensing device and the thermoelectric couple, if the temperature inside the gas refrigerator does not reach a set temperature value, the combustion gas from a combustion unit is automatically ignited to generate heat to drive a cooling unit of the gas refrigerator that can thus keep its low temperature, and the combustion gas can be blocked automatically when in accident flame extinguishing of the combustion unit and in inability of keeping on igniting. One needs not to observe the burning state of the combustion unit when the refrigerator is in use; the present invention can automatically control the combustion unit without a manual adjustment, it is convenient and highly safe for use.
